From 33ea2dcb39ba50b0b69d1b1dc24702f084b46411 Mon Sep 17 00:00:00 2001 From: Sumit Semwal Date: Fri, 27 Jan 2012 15:09:27 +0530 Subject: dma-buf: add dma_data_direction to unmap dma_buf_op Some exporters may use DMA map/unmap APIs in dma-buf ops, which require enum dma_data_direction for both map and unmap operations. Thus, the unmap dma_buf_op also needs to have enum dma_data_direction as a parameter.
